Crabtree can be an awesome player, he pulled down some high passes and made Papaki look good. That said, he could have been on the high ground of that argument and then had to go and fuel it with nothing to back it.
Papaki screwed up going at Sherman, he just solidified the shut down corner argument, then rather than get the ball down, Crabs allowed Sherman to make the controlled tip. I like that. The Niners have "the catch" where the Hawks have "The Tip".
